DIYer, don't try to act all hard by bashing other peoples responses to your questions about safety gear. lol. It's less about people not being able to "take your heat," and more about them not wanting to deal with your ignorance while learning about the topic. Using intelligent caustic phrases like "duh" does not help your argument that you're not being harsh. It leaves me pretty convinced that you are sufficiently uneducated in the topic, which is fine in itself. However, it gets annoying for people when you are not understanding that there are others in the same situation as you. Oh, and I hate to say this because of the way my ego-puffing colleagues use this, but it is directly related to one of your attempted jabs at fellow forum member: I am a rocket scientist. Now, this has nothing to do with my work, but my analysis of this thread is that you are simply unclear of the purpose of an online forum. This is a forgivable mistake, and can easily be cured with a little of your beloved research. Hope you have a splendid day!
